Twin Zygosity DNA Test

Find Out If Your Twins Are Identical or Fraternal with FastestLabs®

Contrary to popular belief, it is not always possible to tell if a set
of twins is identical or fraternal just by looking at them. This is especially
true when the twins are very young. The only way to determine for sure
whether or not twins are identical or fraternal is to conduct a twin zygosity
DNA test. At FastestLabs®, we offer quick and easy twin zygosity testing
with accurate results you can trust.

Whether you are interested in determining the zygosity of your twin children
for medical reasons, to establish eligibility for becoming a blood or
tissue donor, or simply to satisfy your curiosity, you can rely on Fastest
Labs. We make the process easy and always strive to meet or beat any of
our competitor's prices.

Why Schedule a Twin Zygosity DNA Test?

While many people think that determining if twins are identical (monozygotic)
or fraternal (dizygotic) is as simple as looking at them, it can actually
be very difficult to tell twin zygosity without a DNA test. Even commonly-used
indicators of twin zygosity, such as the number of placentas, can be easily
misinterpreted or simply inaccurate.

Identical twins occur when a single sperm fertilizes a single egg and the
embryo ultimately splits into two. Fraternal twins, on the other hand,
are the result of two separate eggs being fertilized by two separate sperms.
It is even possible for fraternal twins to have two different fathers,
though this is extremely rare. While identical twins have the exact same
DNA, fraternal twins have distinct differences in their genetic thumbprint.
Often, this shows up as a difference in looks, though even fraternal twins
can look extremely alike, especially as infants.

Twin zygosity DNA testing can be extremely useful for:

Conclusively determining if a set of twins is monozygotic or dizygotic

Establishing genetic compatibility for blood or tissue donation

Confirming zygosity for other medical reasons, including presence of genetic defects

Satisfying general curiosity or carrying out a fun family activity

No matter your reasons for scheduling a twin zygosity DNA test, you can
trust Fastest Labs for quick and accurate results, every time. We uphold
the strictest standards in the industry for your peace of mind.
